The objective of this study was to evaluate the nutritional characteristics of meat from lambs fed diets containing 0%, 12.5% and 25.0% (dry matter (DM)) mulberry hay as a substitute for the concentrate. Twenty-four feedlot Île-de-France lambs with an average age of 60 days and bodyweight (BW) of 15 kg were fed in individual stalls and slaughtered at 32 kg BW, at approximately 130 days old. The chemical composition of the experimental diets contained, respectively, 584.4, 569.4 and 571.8 g DM/kg; 188.8, 185.1 and 184 g crude protein (CP)/kg and 29.9, 29.5 and 25.5 Mcal/kg DM for the mulberry hay inclusion levels of 0%, 12.5% and 25.0%, with a dietary forage to concentrate ratio of 50 : 50. The chemical composition of the meat was 757.9 g moisture/kg DM, 208.6 g CP/kg DM, 22.9 g crude fat/kg DM and 10.5 g ash/kg DM. Cholesterol concentration (36.07 mg/100 g) in the meat was not influenced by mulberry hay inclusion of the diet. An increase was observed in the concentrations of saturated pentadecanoic, heptadecanoic and arachidic acids; monounaturated heptadecenoic acid; and polyunsaturated α-linolenic, γ-linolenic and eicosapentaenoic acids. Nervonic and conjugated linoleic acid (CLA) concentrations responded quadratically, representing 3.7 g/kg and 5.9 g/kg of the meat when mulberry hay was included at 16.98% and 12.56%. Omega-3 acid concentrations increased, while the omega-3 : omega-6 ratio decreased in the meat of mulberry hay-fed animals. Inclusion of mulberry hay in lamb diets increases the amount of desirable fatty acids in their meat, whose nutritional characteristics are improved.

RESUMO A evolução das linhagens sintéticas de suínos propiciou a obtenção de animais com potencial máximo de deposição proteica em pesos superiores; entretanto o peso ótimo de abate dessas linhagens não é conhecido. O objetivo do estudo foi avaliar o desempenho, características de carcaça e avaliação econômica de 417 suínos da linhagem Agroceres PIC abatidos com 100, 115, 130 e 145kg de peso vivo. Os suínos foram criados em baias com 10-11 machos ou fêmeas, com fornecimento programado de 2,8kg de ração por animal, por dia, a partir de 80kg até os pesos de abate (PA) de 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, e 143.90±1.24. Não houve interação entre sexo e PA (P>0,05). A espessura de toucinho, área de gordura e área de olho de lombo aumentaram linearmente com o PA (P<0,001; R² entre 70,12 e 77,44%), e o rendimento de carcaça aumentou de forma quadrática (P<0,001; R²=24,66%). A porcentagem de carne magra não foi afetada (P>0.05) e a conversão alimentar (R²=43,29%) apresentou discreta piora linear com o PA (P<0,001), mas o efeito sobre o custo de produção (R$/Kg) foi quadrático, com ponto de mínima aos 134,85kg. Conclui-se que, com o manejo utilizado, a elevação do PA resulta em aumento na quantidade de carne produzida sem alteração no seu rendimento e apresenta pouco efeito sobre o desempenho.

Recent genetic improvement has developed pigs with maximum potential for protein deposit at higher weights; however, their optimal slaughter weight still needs to be determined. The objective of the study was to evaluate live performance, carcass traits, and economic viability of 417 Agroceres PIC pigs slaughtered with 100, 115, 130, and 145kg live weight. Pigs were reared in pens with 10-11 barrows and gilts each, offered a feed allowance of 2.8kg/pig/day until the following slaughter weights (SW): 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, and 143.90±1.24. There was no interaction between sex and SW (P>0.05). Backfat thickness, fat area, and loin eye area linearly increased with SW (P<0.001; R2: 70.12-77.44%), and carcass yield increased in a quadratic manner (P<0.001; R²=24.66%). Lean yield was not affected (P>0.05), and feed conversion ratio (R²=43.29%) linearly worsened with SW (P<0.001), but the effect of SW on live production cost (R$/kg) was quadratic, with the minimum point at 134.8kg. It was concluded that, under the applied management, increasing SW results in larger amount of lean tissue with no change in its yield and little effect on growth performance.

Foi avaliada a qualidade da carne e os cortes de suínos abatidos entre 100 e 145kg de peso vivo. Os suínos (417 machos castrados e fêmeas, linhagem Agroceres PIC) foram mantidos sob fornecimento programado de 2,8kg de ração por animal por dia a partir de 80kg até o abate aos: 100,71±0,85, 118,58±0,99, 134,07±1,18 ou 143,90±1,24kg de peso vivo. Destes, 71 suínos foram usados para avaliação dos cortes primários e secundários. Não foi observada interação entre sexo e peso de abate em nenhuma das variáveis avaliadas. Os pesos do pernil, da paleta e do carré aumentaram linearmente (P<0,01; R2entre 84,3 e 93,2%) com o peso de abate, com pouco efeito sobre o rendimento da carne. A coordenada vermelho/verde (valor de a*) aumentou linearmente (P<0,05) no lombo e de forma quadrática (P<0,01) no pernil com o aumento do peso de abate. A força de cisalhamento apresentou resposta quadrática (P<0,05), com redução até o valor mínimo estimado para os 122kg de peso vivo. Conclui-se que, com o manejo utilizado neste estudo, a elevação do peso de abate resulta em aumento na quantidade de carne produzida, com pouco efeito sobre o rendimento de carne. A carne de suínos abatidos em pesos elevados apresenta cor vermelha mais intensa e mesmo nível de gordura intramuscular que a carne de suínos mais leves, enquanto a maciez é alterada apenas de maneira discreta.

Meat quality and cut yield of pigs slaughtered between 100 and 150kg live weight were evaluated. Pigs (417 Agroceres PIC barrows and gilts) were fed a daily allowance of 2.8kg per head from 80kg until 100.71±0.85, 118.58±0.99, 134.07±1.18 or 143.90±1.24kg live weight. Seventy-one pigs were used for the evaluation of primal and subprimal cuts. There was no interaction between sex and slaughter weight for any of the evaluated parameters. Ham, shoulder, and loin weights linearly increased (P<0.01; R2: 84.3-93.2%) with increasing slaughter weight, which, however, had little effect on primal cuts meat yield. Increasing slaughter weight promoted a linear (P<0.05) and a quadratic (P<0.01) increase of red/green coordinate (a* value) of the loin and ham, respectively. Shear force showed a quadratic response (P<0.05), with minimum value estimated at 122kg slaughter weight. It was concluded that, under the applied management, increasing slaughter weight increased the volume of meat, but had little effect on meat yield. The meat of pigs slaughtered at heavier weights showed more intense red color and the same intramuscular fat content as lighter pigs, while tenderness was slightly affected.

O aumento do número de programas de pós-graduação tem sido concomitante a um aumento da produção científica brasileira. Este estudo teve como objetivo compreender o perfil dos pesquisadores brasileiros bolsistas do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) na área de Educação Física. Para tal foram analisados os currículos dos 74 bolsistas, registrados na Plataforma Lattes. Foram consideradas variáveis como gênero, classificação no CNPq (1A a 2), instituição em que atua, tempo de doutorado, quantidade de artigos publicados, bem como a classificação do Qualis da revista, publicações de livros e capítulos de livros, orientações de iniciação científica, mestrado e doutorado e a obtenção de patentes. Para as variáveis relacionadas a publicações, foi considerado o triênio de 2007 a 2009. Os resultados mostraram que a maior parte dos pesquisadores tem entre 5 e 32 anos de doutorado, é do gênero masculino (75,7%), classificados na categoria 2 (67,6%), atuando prioritariamente na região sudeste e, mais especificadamente, no Estado de São Paulo. A maior parte das publicações ocorreu em periódicos nacionais com os Qualis B1, B2 e A2. Observou-se importante número de publicações de capítulos de livros e livros, bem como um número relevante de orientações de mestrado, doutorado e iniciação científica.

The increase in the number of postgraduate programs has been accompanied by a concomitant increase in the Brazilian scientific output. The aim of this study was to describe the profile of the Brazilian researchers with Productivity Grants in the Brazilian National Research Council (CNPq) in the Physical Education Area. The curriculum of the 74 scholarship researchers in the Lattes Platform was analyzed. The researchers varied in gender, classification in the CNPq (1A to 2), institution, date of graduation, number of papers published; as well as the classification of the journal in the Qualis, book and book chapter publications, supervision of undergraduate scientific initiation, masters and doctorate students, and the patents they had obtained. The study considered publications from 2007 to 2009. The results show that most of the researchers had between 5 and 32 years of doctorate studies, are male (75.7%), classified in category 2 (67.6%), with a large proportion working in the south-east region, particularly in the state of São Paulo. Most publications are in the national periodic Qualis B1, B2 and A2. A large number of books and book chapters were published, and there were an excellent number of supervisions of undergraduate and postgraduate students.

Signalgrass is largely planted as cultivated pasture in Brazil, but no management targets have been identified. The objective of this study was to evaluate daily herbage accumulation rate (HAR) in Signalgrass pastures grazed at two intensity x two frequency treatments using steers. Target intensities corresponded to 5 and 10 cm post-graze sward height and frequencies were determined by pre-graze sward light interception (LI = 95 or 100%) by the canopy. The trial was carried out from January 2007 to April 2008 on an Entisol. Less frequently grazed pastures had higher HAR during the entire period (29 and 36 kg/ha for 95 and 100%-LI, respectively). There was no intensity effect on HAR, except in the 2007 summer season (January to March) when pastures grazed to 10 cm had a higher HAR (59 kg/ha) than those grazed to 5 cm (45 kg/ha). Total leaf yield increased when regrowth was longer (7930 vs. 8729 kg/ha for 95 and 100%-LI, respectively), but stem and dead material yield increased as well (4877 vs. 7155 kg/ha for 95 and 100%-LI, respectively). The advantages of extending the rest period due to increased HAR was counterbalanced by the great influence of stem and dead material, decreasing pasture leafiness and likely forage nutritive value on the grazed stratum.

The vibrational spectra (FTIR-Raman) of the hexaaquatris(malonato)dieuropium(III) dihydrate are reported and discussed. An assignment of H2O, CH2 and OCO modes in the complex is proposed on the basis of the structural data previously reported. Valuable information about the water librational modes has been obtained. The different types of interaction between the carboxylate groups of the malonate ions and Eu(III), four- and six-membered chelate rings and monodentate bridging interactions, have been also evidenced. The mechanism of the thermal dehydration is aalysed and the results are in agreement with the crystal structure.

En este trabajo se presentan y discuten los espectros vibracionales (FTIR-Raman) de hexacuotris(malonato)dieuropio(III) dihidrato. Se propone una asignaciónde los modos asociados a H2O, CH2 y OCO de acuerdo con los datos estructurales reportados en literatura. Fue posible obtener información valiosa sobre los modos libracionales de agua. Se evidenciaron también los diferentes tipos de interacción entre grupos carboxilato del malonato con el ion Eu(III), con presencia de anillos de cuatro y seis miembros e interacciones monodentadas. El mecanismo de la deshidratación térmica resultó consistente con las interacciones descriptas en la estructura cristalina.

O perfil antigênico de 45 herpesvírus (44 de bovinos, sendo seis amostras de referência de BHV-1 e 15 prováveis BHV-1; três amostras de referência de BHV-5 e 20 prováveis BHV-5) e uma amostra de herpesvírus bubalino (BuHV) foi examinado com um painel de anticorpos monoclonais (Acms) produzidos contra antígenos de herpesvírus bovinos. Para os exames, foi utilizada a prova de imunoperoxidase (IPX) sobre cultivos de células infectadas, tendo os Acms como anticorpos primários. A determinação dos padrões de reatividade das amostras de vírus frente aos Acms permitiu a diferenciação entre os tipos 1 e 5. Todas as amostras isoladas de casos de encefalite apresentaram perfil de BHV-5. Quatro amostras de BHV-5 isoladas de áreas geograficamente distintas apresentaram perfís de reatividade diferenciados em relação às demais amostras do tipo 5. Duas amostras de vírus com perfil antigênico de BHV-5 foram isoladas de sêmen de animais infectados. Estes resultados comprovam a utilidade da caracterização antigênica com este painel de Acms na tipagem de amostras de BHV-1 e BHV-5.

The antigenic profile of 45 herpesviruses (44 viruses from cattle, including six reference BHV-1 strains and 15 putative BHV-1; three reference BHV-5 strains and 20 putative BHV-5) and one buffalo isolate (BuHV) were examined with a panel of monoclonal antibodies (Mabs) prepared against bovine herpesvirus antigens. Tests were performed by immunoperoxidase (IPX) on infected cell cultures, with the Mabs as primary antibodies. Immunostaining allowed the differentiation between types 1 and 5 viruses. All isolates from cases of encephalitis displayed BHV-5 profiles. Four BHV-5 isolates obtained from geographically distinct areas displayed different and highly variable IPX patterns of reactivity. Two viruses with BHV-5 antigenic profile were isolated from semen of asymptomatic bulls. The results showed that the antigenic characterization with the Mab panel employed here is useful for typing BHV-1 and BHV-5 isolates.
